摘要
确保轧件旋转条件,是建立楔横轧正常轧制过程的先决条件。在工艺条件相同的情况下,轧件旋转最困难的区域,不是楔入起始段,也不是楔展宽成形段,而是在楔入段升至最高点前后轧件旋转半周(θ=π)区域内。这不仅为实践所证明,而且导出的旋转条件公式,证明了上述结论。
To insure the rotation of rolled parts is the fundamental condition for building normal rolling process in cross wedge rolling. Under the same technique, there will be a most difficult area to rotating the part, it is neither in the begining nor in the stretching shaping part of the wedge, it is around the highest point of the wedge from its begining where the rolled part rotates about half a circle (θ=π). It has been demonstrated by not only practice also the formulas of rotatory condition.
